Glyceryl Stearate
Glyceryl stearate or Glyceryl monostearate is a waxy ingredient that is obtained from coconuts, palm kernels, or olives. It is usually pale yellow or white in color. Glyceryl Stearate is used in skin care and cosmetic products because of its great moisturizing properties. It traps moisture on the skin and hair to prevent dehydration and damage. Moreover, glyceryl stearate also binds other ingredients together in a formulation. Further, this ingredient is mildly comedogenic and may cause acne on some skin types. The chemical formula of Glyceryl Stearate is C21H42O4.

What is GLYCERYL STEARATE used for?

Glyceryl stearate provides multiple benefits for the skin and hair. This is why it is used in thousands of cosmetic, skin care, and hair care products such as skin cleansers, foundations, eyeliners, and shampoos.
  • Skin care: It is a humectant that draws water to the top most layer of the skin and binds it there to provide intense hydration. It also acts as a thickener to maintain the texture and spreadability of the products
